United States Patent() 3,448,852 TAPE HOLDING ROLL Robert M. Dunning, St. Paul, Minn., assignor to Hoerner Waldorf Corporation, St. Paul, Minn., a corporation of Delaware Filed Mar. 1, 1968, Ser. No. 709,722 Int. Cl. B65h 55 /00, 75/02; B65d 85/04 U.S. Cl. 206-52 10 Claims ABSTRACT OF THE DISCLOSURE The invention discloses a holder for an object having a. generally cylindrical aperture therein or therethrough. A generally circular locking means is formed in the surface of a sleeve enclosing the object, this locking means being supported by two or more supporting means which permit the locking means to be forced into the aperture to prevent lateral movement of the object relative to the sleeve.

This invention relates to an improvement in tape roll holders wherein it is desired to provide a means of enclosing an object having a generally cylindrical aperture into which locking means may extend to hold the object from lateral or longitudinal movement.

Various types of packages have been used to contain cylindrical objects such as rolls of tape wound about a hollow cylindrical core. It is desirable to hold such an object in spaced relation to the walls of the outer enclosure so that the periphery of the roll will not be subject to pressure when the rolls are stored with their axis extending horizontally. In many instances it is desirable that the carton be such as to permit the tape to be withdrawn from the roll while the roll remains contained in the package. As a result, open ended sleeves are often used for the purpose, and the means lfor locking the rolls in the carton not only prevent the shifting of the roll in a radial direction, but also permit rotation of the roll about its axis so that the tape may be unwound. It is this type of sleeve which is disclosed in the present case, although it should be understood that end closures may be provided on the ends of the sleeve if they are so desired.

An object of the present invention resides in the provision of a sleeve including two parallel panels which overlie the axial ends of the object, and parallel walls connecting opposite edges of the main panels to form a tube which is generally rectangular in cross-section. One or both of the panels overlying the ends of the generally cylindrical aperture are cut to provide a locking means comprising a body having a generally circular outer edge which is of substantially the same radius as the aperture, and in providing a supporting means supporting the body of the lock from its panel so that it may be offset from the panel in which it is for-med to extend into the aperture. The circular body prevents radial movement of the object in any direction, but does permit rotation of the object about its center so that the tape may be unrolled therefrom.

A feature of the present invention resides in the provision of a sleeve of the type described in which the circular body forming the locking means is divided into a plurality of integrally connected segments provided with arcuate edges having a common center of arcuation. Between the adjacent edges of each pair of segments is located a supporting means which permits the locking means to move axially into the aperture to engage the object contained. This locking means in its preferred form comprises a rst strap which is hinged to the panel containing the locking means to extend inwardly toward the center of arcuation thereof. The outer end of each first strap is hinged to the panel along a fold line which is substantially tangent to the arcuate edges. The inner end of ice each strap is connected along a fold line which is preferably parallel to the tangent fold line to an intermediate section which is wider than the strap and preferably extends laterally to both sides of the strap. The intermediate section of the support is hingedly connected to a pair of second straps which are arranged on opposite sides of the rst strap. The second straps are hingedly connected at their inner ends to the intermediate section of the support and at their outer ends to the segments near the periphery thereof. With this arrangement, when pressure is applied to the locking means tending to force the locking means axially into the aperture, the lirst and second straps hinge relative to the panel and to the segments, providing a zig-zag connection between the generally circular body and the sleeve panel, permitting the segments to be inserted into the cylindrical recess to a desired extent.

A further feature of the present invention resides in lthe provision of a sleeve of the type described in which both of the parallel panels overlying the ends of the. aperture are provided with similar locking means, both of which may extend into the aperture from opposite ends thereof. If the axial length of the tape roll is properly proportioned relative to the diameter of the aperture, the two locking means may be moved into face contact, providing an effective substantially circular support substantially midway between the ends of the aperture which may e'ectively hold the roll from movement.

A further :feature of the present invention resides in the provision of a device of the type described including locking means extending into the aperture from opposite ends thereof, and including interlocking means for holding the locking means in face contact. The locking means may be adhered or stapled in contact but, if so desired, interlocking means may be provided for holding the locking means together.

'v A further feature of the present invention resides in the provision of a device of the type described which may be inexpensively produced, and which lends itself very readily to automation. The objects, such as tape rolls being packaged, are slid into an open end of the sleeve, centered With respect to the locking means, and the locking means is forced into the aperture from opposite ends thereof andinterlocked. Thus the locking means may be locked at a high rate of speed and while the sleeves are in m-otion if it is so desired.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.

FIGURE 8 is a sectional view through the carton illustrated in FIGURE 7.

FIGURE 9 is a diagrammatic view of the blank from which the carton of FIGURES 7 and 8 is formed.

The tape roll holder A which is illustrated in FIG- URES l through 5 ofthe drawings is formed of the blank indicated in FIGURE 5. The blank comprises a substantially rectangular sheet of paperboard which is transversely creased to provide a face panel a wall panel 11, a face panel 12, and a second wall panel 13 which are foldably connected along parallel fold lines 14, 15 and 16. A glue flap 17 is hingedly connected to the face panel 10 along a fold line 19 which is parallel to the previously described lines of fold. When the blank is folded along the fold lines 14 and 16, the wall panel 13 overlaps the glue ap 17 and is adhered to other wise secured thereto. This structure forms an open ended sleeve when the wall panels are folded into right angular relation to the face panels 10 and 12. Obviously, end closure fiaps could be connected to the panels along the edges 20 and 21 extending longitudinally of the blank, if end closures are desired.

The structure shown in FIGURES 1 to 5 includes a locking means having two diametrically opposed supporting means connecting the locking means to the panel in which it is formed. Both of the panels 10 and 12 are shown as including locking means which are indicated in general by the numeral 22. A single locking means may be used in either of the panels 10 or 12, but the use of two such members extending into the object from opposite ends thereto is usually preferred.

The holder or sleeve A is designed to contain an object B which in the arrangement illustrated comprises a roll of pressure sensitive tape 23 which is spirally wound about a relatively rigid core 24. The core 24 is provided with an axial aperture 25 therethrough. Obviously, any object having a substantially centrally located cylindrical recess therein could be used in place of the tape roll B.

As indicated in FIGURE 5, each locking means 22 is substantially identical to the other, differing therefrom only in the means of interlocking the two locking means in face contact. As indicated, each locking means includes a pair of segments -26 and 27 which are integrally connected along the center portion 29 of the locking means. The segments 26 and 27 are defined along their outer edges by arcuate cut lines 30 and 31 respectively which are coaxial or are provided with a common center of arcuation. The ends of the segments 26 and 27 are separated by supporting means which are indicated in general by the numeral 32. Each supporting means 32 includes a first strap 33, the outer ends of which are connected to the remainder of the panels 10` and 12 by fold lines 35 which are substantially tangent to the circle formed by the outer edges of the segments 26 and 27. In other words, the fold lines 35 connect adjoining ends of the cut lines 30 and 31 and actually comprise a chord of the circle partially formed by the cut lines 30 and 31. Each first strap 33 is hingedly connected at its inner end by a fold line 36 to an intermediate portion 37. In the particular arrangement illustrated, the intermediate portions 37 are generally V-shaped in form, although this is somewhat of a matter of choice. The intermediate portion 37 -of each supporting member 32 is connected along fold lines 39 to second straps 40` which extend outwardly toward periphery of the arcuate segments 26 and 27. The fold lines 37 are shown in angular relation to the fold line 36 of each supporting member, and extend from opposite ends of the fold line 36. The second straps 40 are connected by fold lines 41 to the segments 26 and 27, the fold lines 41 preferably being parallel to the corresponding fold lines 39. With this arrangement, the locking means including the segments 2.6 and 27 and the connecting portion 29 may be exed out of the plane of the remainder of the panel 10. Because of the fact that the supporting portions 32 are similarly formed, the locking portion including the segments 26 and 27 have a tendency to remain in parallel relation to the remainder of the panel 10.

A pair of U-shaped cut lines 42 are provided in the segments 26 and 27 of panel 10, the U-shaped cut line having their sides substantially parallel to radial line extending through the center of the cut line. A fold line 43 connects the sides of each U-shaped cut line 42 to permit the tab defined by the cut line to fold out of the plane of the segments 26 and 27 The similar locking means 22 in the panel 12 is provided with a pair of generally arrowhead cut lines 44 which are somewhat wider than the cut lines 42 and project laterally therebeyond. The cut lines 44 are connected by fold lines -45 which substantially coincide with the fold lines 43 of the locking means in the panel 10 when the two locking means are in face contact. The tabs 46 defined by the cut lines 44 may accordingly be forced through the openings in the segments 26 and 27 of the locking means in the panel 10 when the two locking means are in face contact. When forced through the openings, the ears 47 project laterally beyond the cut lines 42 and act to lock the looking means of the panel 10 in face contact to the locking means 22 in the panel 12 as indicated in FIGURES 3 and 4 of the drawmgs.

When locked in face Contact, the combined locking means 22 are positioned substantially half-way between the planes of the panels 10 and 12 as indicated in FIG- URES 3 and 4. Preferably the arcuate cut lines 30 and 31 defining the outer edges of the segments 26 and 27 are of suficiently small diameter so that the roll core 24 may rotate relative to the locking means. As a result, tape may be unwound from the core as it is needed while the core remains in position in the sleeve.

FIGURE 6 of the drawings shows an arrangement which is very similar to that previously described out which differs therefrom only in detail. The panel 10a is provided with a locking means 49 including a pair of opposed segments 50 and 51 connected by a central connecting portion 52. A pair of diametrically opposed first straps 52 are hingedly connected to the panel 10a along parallel fold lines 53 which connect the opposed ends of the arcuate cut lines 54 and 55 which define the outer edges of the segments 50 and 51. The inner ends of the straps 52 are connected by parallel fold lines 56 to intermediate portions 57 which extend laterally to opposite sides of the straps 52.

A pair of second straps 59 are connected to the intermediate portion 57 of each support along extensions of the fold line 56. The straps 59 extend outwardly toward the periphery of the segments and are connected to the segments by aligned fold lines 60 which are parallel to the fold lines 56. The first straps 52, intermediate portions 57, and second straps 59 form a connecting support which folds into zig-zag form when the locking means 49 is forced axially out of the plane of the panel 10a and int-o the cylindrical recess of the object being supported.

The structure shown in FIGURE 6 functions similarly to the structure shown in FIGURES 1 through 5 except for the fact that the fold lines connecting the first straps to the intermediate portion and supporting panel. This structure has a tendency to fold more readily than the structure of FIGURES l to 5, but has somewhat less lateral stability than Where the fold lines at the ends of the second straps are angularly related to the fold lines at the ends of the first straps.

FIGURES 7, 8 and 9 of the drawings show another modified form of construction which is very similar to that shown in FIGURES 1 to 5 of the drawings, but in which the locking means are provided with three angularly spaced supports in place of the two illustrated in FIGURES 1 to 5. The purpose of this modification is to indicate that any desired number of supporting means may be provided, depending upon the size of the object. For example, if the object being contained was provided with an aperture of large diameter, it is possible that a considerable number of supporting means be provided. When a roll of tape of conventional size is being contained, the number of supporting means would probably not exceed three due to space restrictions.

The tape roll holder C illustrated in FIGURES 7, -8 and 9 is formed of the blank illustrated in FIGURE 9.

The blank includes a face panel 61, a first wall panel 62, ya second face panel 63, and a second Wall panel 64 connected along parallel fold lines 65, 66 and 67. A glue ap 69 is hingedly connected to the face panel 61 along a fold line 70 `which is parallel to the previously described lines of fold. A locking means 71 is provided at the center of the face panel 61, and a similar locking means 72 is provided in the face panel 63. When the panels described have been secured in tubular relation, the locking means 71 and 72 are axially aligned or concentric.

Each locking means 71 or 72 includes three angularly spaced segments 73, 74 and 75 which are connected by a central member 76. The segments are provided with arcuate outer edges 77, 79 and 80 which have a common center of arcuation to define a generally circular locking body. A series of first straps 81 are hingedly connected at their outer edges by fold lines 82 which connect adjacent ends of the arcuate cut lines. The inner ends of the straps 81 are connected by fold lines 83 to intermediate portions 37 of the previously described structure.

The intermediate portions 84 extend to opposite sides of the straps 81 and are hingedly connected along fold lines 85 to second straps 86 which extend outwardly toward the periphery of the segments. The outer ends of the straps 86 are connected along fold lines 87 to the various segments near the periphery thereof. The fold lines 85 and 87 are shown angularly related to the fold lines defining the ends of the first straps 81.

The structure C operates very similarly to the previously described structure A. In other words, when the generally circular locking means 71 and 72 are forced out of the plane of the panels 61 and 63 in which they are formed, the first straps 81 fold into zig-zag relation to the center portions or intermediate portions 84 and the second straps 86 to support the locking means in generally parallel relation to the panels to which they are connected.

The center of the locking means 72 is shown as including a trapezoidal fiap 89 hinged to the locking means near the center thereof. The end of the trapezoidal flap 89 is somewhat Sider than the rectangular flap 90 in the locking :means 71 so that when the flap 89 is forced through the opening formed by flexing the liap 90, the

two locking means will be secured substantially in face contact.
